Upgraded project to Godot 4.5

[jonjondev]

Pull Request Description

This PR upgrades the project Godot version to 4.5. Beyond automatic data updates, the @abstract decorator was applied across all classes and functions relevant in the project, variadic arguments were substituted on all logging utils (which were moved to their own namespace), and an editor script was added for validations.

Please make sure the build is working correctly across the pipeline and all editor tools are functioning as expected before merge.

The PR has been...

• provided a reasonable name that is not just the branch name (e.g "Implemented walls mechanic")
• linked to its related issue (if any)
• assigned a reviewer from the team

The code has been...

• made mergable and free of conflicts in relation to the base branch (according to GitHub)
• pulled to the reviewer's machine and reasonably tested
• read through and approved by a reviewer
• bumped in project version over the latest release (i.e. vX.Y.Z for major, minor or patch)

Note: for new features, use minor (Y), and for bug fixes or small changes, use patch (Z). Bumping the minor version should also reset the patch version to zero, so v1.2.4, would become v1.3.0. See semantic versioning for more info.

All looks good and runs fine, so those removed fields are ok
